HENRI JULES DE LISLE DE SALES, OF PARIS, FRANCE.

VAPORIZING-BURNER.

T all whom it may concern:

Be it known that I, HENRI JULEs DE LIsLE DE SALEs, engineer, citizen of the French Republic, residing at Paris, Department of Seine, France, having post-office address at 12 and 14 Passage des Princes, in the said city, have invented certain new and useful Improvements in. vaporizing-Burners, of which the following is a specification.

This invention relates to a vapor burner for incandescent-mantle-lamps, and the primary object of the same is to'provide a simple and effective device of this character especially adapted for burning spirit and embodying means whereby the spirit or fuel may be regularly and advantageously fed to the burner proper and adjustable as to the quantity fed. 1

In the drawing: Figure 1 is a sectional elevation of the lamp embodying the features of the invention. Fig. 2 is a longitudinal vertical section on a slightly enlarged scale of portions of the lamp and particularly illustrating the needlevalve. Fig. 3 is a section on a slightly enlarged scale through the diametrical plane of the lamp.

Similar characters of reference are employed to indicate corresponding parts in the several views.

The lamp comprises a tubular frame 1 cmbodying two members depending from the bottom near opposite extremities of a superheating chamber 8. Projecting outwardly from opposite sides of the chamber 8 and in alinement with each other are horizontal tubes 2 and 2 the tube 2 having a needle valve 8 disposed therein and provided with a hand-wheel or analogous turning device at its outer extremity as shown, the said handwheel or analogous turning device being of usual form. The other branch or tube 2 is connected when operatively applied to a suitable spirit tank or fuel supply means, not shown, by'a tube 4 communicating with the outer extremity of the pipe 2, and within the latter is a diffusing or cleaning device consisting, in this instance, of a brush 5 formed with metallic threads and which fills the interior of the said tube 2. The brush carries on its outer end a ring 6 for convenience in removing and applying the same, and over the outer end of the tube 2 is removably fitted a screw cap or closure 7. The inner end of the tube 2 within the chamber 8 is formed with a reduced opening 9 for engagement of the inner reduced end of the needle Specification of Letters Patent.

valve 3. The tubular frame members depending from the superheating chamber 8 are connected at their lower extremities to a screw-tapped piece 11 on which is screwed a nozzle 12 provided with a very small opening in the upper extremity. Surrounding the lower extremities of the tubular frame members, the piece 11 and the nozzle 12 is a col lecting member 1.8 in the form of a cupshaped collar and secured to the lower end of the piece 11 by a screw-device 19. The function of this collecting member is to hold the drops of spirit which may fall or gravitate through the tubular frame members and run out through the nozzle in the preliminary or starting operation or during the opening of the needle valve.

With the device as thus far described a Bunsen burner is used and consists of a tube 13 which is adapted to be inserted and movable in a socket or sleeve 14 carried by the frame members depending from the chamber 8 as shown by Fig. 3. On the upper part of the body of this burner a wire gauze cap 15 is mounted and has a stem 16 with an upper tapered extremity. The wire gauze cap is maintained upon the upper portion of the body of the burner by means of a ring 17, the internal diameter of the latter being about the same as the external diameter of the part of the body which it engages. When the mantle is put in its place its lower part surrounds, to a sufficient extent, the upper part of the burner. The mantle depends over the upper extremity of the. burner and is suspended from a hook 10 secured to the bottom of the superheating chamber 8.

In addition to the function of the cupshaped collar hereinbefore explained it is also intended to serve as a starting or pilot means and the spirit that is run thereinto or which may be placed therein by any suitable means is ignited and heats the chamber 8, the spirit being admitted to this chamber by properly opening the needle valve 3, and within the said chamber the spirit is vaporized and passes down through the frame members to the nozzle 12 and from the latter fed or directed to the burner disposed above the said nozzle as hereinbefore explained. As the vapor passes up into the Bunsen burner it draws the surrounding air in sufficient quantity into the said burner therewith, thus setting up an advantageous mixture of the combustible vapor and air. The spirit which is fed to the tube 2 through the tube 4.

will become heated and cleansed with advantage in quick vaporization and cleansing of the spirit. It will therefore be seen that the spirit is fed into the chamber 8 in a condition conducive to the acceleration of the formation of vapor.

Having thus described the invention, what is claimed as new, is:

1. A burner of the class described, comprising a superheating chamber, tubes ex tending outwardly from opposite sides of the chamber, and in alinement with each other, the one tube having a reduced opening at its inner end within the chamber and the other provided with a needle valve to cooperate with said opening, a brush removably mounted in the tube having the reduced. opening at its inner end, means connecting with the outer extremity of the tube carrying the brush for supplying the said tube with spirit, the spirit being delivered to the outer extremity of the brush, tubular frame members depending from the bottom at opposite extremities of the superheating chamber, a nozzle with which the lower extremities of the tubular frame members communicate, and a burner supported by the frame and mounted directly under the superheating chamber over the nozzle.

2. A burner of the class described, comprising a superheating chamber, tubes communicating with opposite sides of the said chamber and extending outwardly from the latter in alined relation, the one tube having a reduced opening at its inner end within the chamber and the other provided with a needle valve projectable through its inner end to cooperate with the reduced opening in the "first named tube, a diffusing device in the tube having the reduced opening at its inner end, means for feedlng a spirit fluid to the outer extremity of the tube carrying the diffusing device, tubular frame members de pending from the bottom of the superheating chamber, a screw tapped piece with which the lower extremities of the tubular members connect at opposite points, a nozzle fitted in the upper extremity of the screw-tapped piece, and a burner supported by the frame members over the nozzle.

3. A burner of the class described, comprising a superheating chamber, tubes communicating with opposite sides of thesaid chamber and extending outwardly from the latter in alined relation, the one tube carrying a needle valve projeotable through its inner end and the other tube having a reduced opening at its inner end for engagement by the needle valve, a diffusing device in the tube having the reduced opening at its inner end, means for feeding a spirit fluid to the outer extremity of the tube carrying the diffusing device, tubular frame members depending from the bottom of the superheating chamber, a screw-tapped piece with which the lower extremities of the tubular members connect at opposite points, a nozzle fitted in the upper extremity of the screw-tapped piece, a collecting member surrounding the lower extremities of the tubular frame members and connected to the tapped piece, and a burner supported by the frame members under the superheating chamber over the nozzle.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
